Open Source iPhone App Store Apps List – 39 So Far!
Welcome to the fourth iteration of the open source iphone app list. For those that have seen similar listings on other sites using the exact wordings, and links below welcome to the source for the original list.
It can be tough to learn how to develop, especially when it comes to finding complete examples. That’s why I put this list together. Each of these apps has been in the app store, and all but one are in there right now. So if you’re looking for an example of some real apps here they are.
Update: While not a complete game after seeing many interested in open source iPhone games, but having trouble understanding the code I decided to create an extensive iPhone Action Game Programming Tutorial which can be found here.
Note to potential content thieves: I was amazed by the number of human edited sites that flat out copied this list without any attribution of any type (even the descriptions).. it seems so many copied that the original page on ManiacDev.Com (where I hope you’re reading this..) vanished from Google which wasn’t cool. While this may just be a list it takes me hours each time I post it to put it together, find new apps, and check the links.
If you feel you have to copy this list in an effort to make a quick buck (I know the lack of money makes people do stupid things) I’ve got a better alternative for you… why not write a post about your favorite apps from this list, and link back to this page? I’ll even give you a link back in the form of a trackback. We’ll both get more visitors.
Update: Aug 13, 2010 – Added iStrobe and Ecological Footprint Apps

Thanks for this list. Strip Password Manager and Data Vault is also open source/peer reviewed. Maybe you can add it! Here's the website: http://getstrip.com/
Hi Alena, how can I download the source code of Strip Password Manager? I followed the link to the site, but I can not find the link to download the sources?
Thanks.
The “Ecological Footprint” iPhone application has gone free on the App Store and also Open Source now.
It demonstrate the use of the Core Data to access multiple linked tables and show how to query information on a SQLite DB. It shows an example on share the result of Footprint calculation via Mail or Facebook account making use of the framework fbconnect-iphone available freely on internet.
The application doesn’t intend to make a complete calculation of the footprint, which involves a lot of variables and complex parameters, but allows you to understand the importance of our daily consumptions on the Earth planet.
Hope you enjoy with it.

Hi Paolo,
Thanks for making this open source. However, the link to the zip file does not seem to work.
I’ve fixed the zip filename on the server. Now the link works! I’m sorry for the inconvenience.
Hi ReallyCurious. I’ve fixed the problem, now the link works.
Hi Paolo. The open source encryption engine for Strip Password Manager can be found at http://github.com/sjlombardo/sqlcipher
To put it more precisely: The Strip Password and Data Vault app is not open-sourced. Only the used encryption library is? Did I understand this correctly?
